This unit is working excellent for me I was in an accident two years ago and because of nerve damage I must stay in a cool area. I can set this unit on 66° or even 65° and it cool a very large area in my house to this degree. So I am very pleased with the performance of this air conditioning. I love that you can adjust the temperatures to whatever you need and also the fan speed. It has made my life a little better with being able to control the environment I'm sitting in. I have a large AC unit but it is very expensive to use it and run it at 66 degrees for the entire house, so this unit can cool whatever I need it to down to that temperature without running up my light bill. I absolutely I absolutely love this air conditioning.
